.ne Witt Ramsey, Miami, Fla. Application August 2, 1945, Serial No. 608,524 I 3fC lai ns. (01." 16 168) The invention relates to a pivot and bearing therefor, and more especially to a turnable louver or slat mounting for blinds, as for example, Venetian blinds or the like.

The primary object of the invention is the provision of a mounting of this character, wherein pivotal connections can be had between the louvers or slats and the upright operating parts for the turning of the louvers or slats in a blind or the like, the pivot and its bearing adapted for anchorage in the louver or slat and the upright next to the end thereof without causing splitting of these parts when driven or pushed home to effect pivotal connection therebetween.

Another object of the invention is the provision of a mounting of this character, wherein the slat and operating part therefor are securely connected together for relative movements thereof with respect to each other, and without anchorage loosening resultant from wear or hard usage imposed on the blind or the like, the mounting being a bearing assembly of novel construction and is susceptible of adjustable fitting.

A further object of the invention is the provision of a mounting of this character, wherein the same is smooth in operation, neat in appearance, and positive in holding qualities.

A still further object of the invention is the provision of a mounting of this character, which is simple in construction, thoroughly reliable and efiicient in operation, strong, durable, readily and easily applied, eliminates damage to the parts to which it is fitted, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which shows the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a side elevation, partly broken away, of a mounting constructedin accordance with the invention and detached from the blind.

Figure 2 is an end view thereof.

Figure 3 is a view similar to Figure 2 looking toward the other end of the mounting.

Figure 4 is a fragmentary side elevation of a blind having its slats or louvers fitted with the mounting in accordance with the invention.

Figure 5 is a partial sectional view taken on the line 55 of Figure 4 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a portion of a blind, which is of the louver or slat type, certain of the louvers or slats being denoted at l0, while the upright operating members H for such slats or louvers are pivotally connected thereto bya mounting constituting the present invention and hereinafter fully described.

The mounting in accordance with the invention comprises a tubular bearing ferrule l 2, having at one end a folded-over out-turned annular flange or rim l3, while the other end has an internally beveled surface forming a circular knife edge It at this end.

Adapted to telescope within the ferrule I2 is a pivot member involving an elongated tubular stem or shank [5, which at the innermost end thereof is formed with an annular internally beveled surface forming a circular knife edge l5, while at the outer or other end of this stem or shank is formed on out-turned annular flange providing a circular head H at this end.

In the assembly of the mounting the ferrules 12 are driven or pushed into the ends of the louvers or slats ll] of the blind A, at the proper points thereof to have the flanges or rims i 3 contact the ends of the slats or louvers, the sharp knife edges It being adapted to cut their way into the slats or louvers l0 withcutoutward spreading of the fibre thereof, as the latter crowds within the ferrules during driving thereof to place, and thus avoiding the splitting of the slats or louvers at such time of mounting.

The upright operating members I I of the blind A, are provided with openings for the reception of the stems or shanks l5 of the pivot members. The stems or shanks l5 extend into the slats or louvers 10 for telescopic fitting of portions of such stems or shanks in the ferrules I2, as best seen in Figure 5 of the drawing. The flanges creating the heads I! contact with the outer side faces of such members II. In this manner the operating members II are swingingly connected to the slats or louvers H1, or the latter are swingingly connected thereto for pivotal fitting therebetween, to permit adjustment of the blind A from full-line position in Figure 4 to the dotted line position therein or vice-versa. The heads I! of the pivot members are recessed in the outer sides of the members ll.

What is claimed is:

l. A mounting for pivotally connecting movable parts adjacent to each other, comprising a ferrule of tubiform having an inwardly beveled knife edge at one end adapted to be driven in one part, and a tubiform shank loosely fitted in the other part and telescoped into the ferrule and having an inwardly beveled knife edge at one end adapted to be driven in the part having the ferrule.

2. A mounting for pivotally connecting movable parts adjacent to each other, comprising a ferrule of tubiform having an inwardly beveled circular knife edge at one end adapted to be driven in one part, a tubiform shank loosely fitted in the other part and telescoped into the ferrule and having an inwardly beveled circular knife edge at one end adapted to be driven in the part having the ferrule and a rim-flange formed on the other end of the ferrule for disposition between the parts.

3. A mounting for pivotally connecting movable parts adjacent to each other, comprising a ferrule of tubiform having an inwardly beveled circular 4. knife edge at one end adapted to be driven in one part, a tubiform shank loosely fitted in the other part and telescoped into the ferrule and having an inwardly beveled circular knife edge at one end adapted to be driven in the part having the ferrule, a rim-flange formed on the other end of the ferrule for disposition between the parts and a head at the other end of the pivot shank for contact with part loosely fitted therewith.
